RADIATOR.

Be itA known that I, Georgen NV. FnAzrnR, a citizen Vof the United States, 'and a resident of Oakland, in the county of Alameda and State of. California, have' invented a new anduseful Improvement in Radiators, of

which the following is a specification.

My invention is an improvement in radiators, and has for its .object to provide a device of the character specified, especially dator is of that character shown in my coending application, Serial No. 879,315, tiled ecember28, 1914, that is, the said radiator is'detachable `and removable from the vehicle, and wherein a particular type of conlar type of radiator.

In `the drawings :.-Figure 1 is ya front viewof the improved radiator, and Fig-, 2 is a section on the line 2-2 of Fig. 1, lool;- ing in the direction of the arrows adjacent to the line.

1n the present embodiment of the inven-| tion, the improved radiator comprises an outer section and an inner section, each in the formofa rectangular frame, the outer section or frame consisting of upper and lower cross members 1 and '2, and side members or columns 3, the columns connecting the adjacent ends of the upper and lower members to form a continuousreceptacle.

' The outer frame is adapted for connection with the water jacket of the engine.

The inner frame consists of side members or columns L1, an upper connecting cross member 5 and a lower connecting cross member 6, the members 4, 5 and 6 being continuous and 4forming a continuous receptacle or holder for the water. The iriner frame is of a size to' vlit within the outerframe as shown, and the said innerframe is .connected to the upper member 1 and to the lower member 2 of the outer frame. The connections are similar, one connection being, ar-A rangedv between the adjacent members 1 and 5 of the frame,^and two connections being arranged between `the adjacent members 2 and 6. Each ofthe said connections comprises 'apair. of connectingr or 'coupling sleeves 7 and 8, eachof the said sleeves having a marginal iian'ge` 9 at its meetin being arranged between the angesjQ, and

bolts andnut's l1 arerpassed through reg:

istering openings in the langes outside of' the gasket. The nutsare turned to tighten the iianges on the gasket to make a fluid tight joint, and each ofthe nipples or-coupling members 7 and 8 has a. marginalextension 12 at its outer end for connection j I withithe adjacent member 1, 2, l5 or. 6, as

the case may be. Each ofthe coupling members 7 and 8 is arranged around an4 opening'.

in the adjacent member of .the rame,so Vthat there is a free circulation through .the coupling members between ythe iframes.'A lt will be noted that the membersf. and. 6l of. the inner frames have inwardly .oii'set .portions 13 at thecouplings, 'thesaid inwardly oliset portions being connected to the members at each end by a connection 14. Thus a space or recess is provided between .the

coupling. The inner section comprises in addition inner and outer-ring portionsl and 16, respectively, eiachv. of thering pofr tions' being in fact an annular casing, and

'the inner ring portion is connected to the outer ring portion, while' the outer ring portion is connected to the frame of the inner sectionin a manner to be described Tubes 17 connect the innerring portion to the outer ring portion and tubes 18 con.

nect the outer ringportion with' the frame 4 5-6. The tubes 17 are of uniform cross Thot-*tubes 17 which connect the innerring frames` at the couplingv for receiving the v 15 with the outer ring -16 arearranged in series transversely of the radiator, three tubes being provided in each series in pthe present instance. zfllhetubes have their ends .i inserted in registering openings19 and 20"` in the rings 15-and 16, `respectively,I and the ends are then expandedas shown topre-` vent displacement thereof 1in either direc tion. The tubes 18 are xsimilarly arranged,

each tube havingits'large end insertedvin A an'opening 21`in theperiphery of the.outer ring,

lan opening QQ'in'the'innerfs'urface ofthe in and having', its small end` inserted vin parting ner frame. Thus there is a freecirculation of water between the rings 15 and l16, and between the said ringsi and the inner frame, and there is a circulation of the water from, the outer frame to the inner frame by way of the connectionsf7-8. It will be noted from an inspection of Fig. 1 that the tubes 17 radiate in every direction from the inner ring 16 and that similarly the tubes 18-radiate in'every direction from the outer ring 15 to the inner frame Il-5-6- That portion 23 of the radiator wit-hin the interior of the inner ring 16 is open for the circulation of air, and the air isfree to pass between and around the tubes 18 and between and around the tubes 17, as well as between and around the rings 15 and 16 and the inner frame.

concavo-conveX shield or hood 24 is arranged within this space `23 at one end thereof, the said shield or hood being of perforate material and having its convex face outwardly. The upper member 1 of the outer .frame is provided withthe usual tilling nipple 25, having the cap V26. Preferably the tubes 17 and 18 are of corrugated material, that is, the walls of the tubesare corrugated to provide a larger radiating surace. f

VThe inner section of the radiator is the radiator proper, that is', it is this portion ofthe radiator which does the cooling of the water, and it will be evident that the said portion may be easily detached and released from the holding frame or outer section, merely by removing the bolts 11. The entire cooler or radiator proper may be then slipped outward from within the holding -.me. All that part of the radiator which 1s liable to get out of order or to be injured is detachable and removable, and it is not necessary to dismantle the vehicle to obtain access to the radiator.

It will be evident that the cooling tubes of the improved radiator might be arranged in many diiiierent manners, and might vary greatly in size and capacity without defrom the spirit of the invention.

he improved radiator consists in effect of a supporting frame, and a radiator proper adapted and arranged to fit within the supporting frame, the frame and the radiator having inter-engaging means for permitting them to be connected. together operatively and to secure the radiator proper in place in its supporting frame.

It will, be evident from the description that the radiator body may be moved out oi the frame by movingr the said body laterally with respect to the plane of the body and trame, the arrangement being such that the body is detached by a forward movement in the present instance.

lt' will be evident that the supporting frame is not necessarily rectangular', since y 1,1sle,357

itis obvious that it might be circular` or have any other contour proyided that the -cooler or radiator proper had its exterior to lit within the supporting frame.

It will be noticed that the improved ra diators have drain valves at their lowest point for permitting the radiatory proper to be drained to prevent freezing and the like. he concavo-conveX shields are at the front of the radiators. f

claim 1. -A radiator, comprising a substantially rectangular tubular supporting frame adapted for connection with the engine to be cooled and a radiator body fitting within the frame and having inwardly offset portions at its top and bottom and detachable couplings between the inwardly offset portions and the supporting frame for operatively connecting the cooler to the supporting frame, each of the said couplings comprising nipples connected with the supporting frame and the inwardly offset portions of the cooler frame at one end and abutting at the other end. A
